I know there have been previous discussions about the availability of Delo 400 oil, and there are not many places in Pensacola that sell it. I did notice that our Sam's Club has just started stocking it, so that may be true of Sam's in other locations.
The Delo 400LE (Low Emmission) is $56.88 for a case of 6 gallons ($9.48 gal). Of course, this won't affect the serious maintenance guys who buy their oil by the barrel.
